I am trying to boot VxWOrks using tftp for zynq.
I have set the enviroment varibles for ipaddr, serverip, netmask accordingly and files are loaded in RAM succesfully. however, i get the following error when trying to boot the vxWorks image. There is not problem with the VxWOrks image as i can successfully boot with these iamges when i write these files to SDcard and boot from the sdcard

I am trying to setup a Raspberry Pi Zero as a mass storage with dwc2 and g_mass_storage (using the last Raspbian image available).
I created the data storage file with dd, made it a FAT32 fs with mkdosfs.
I looked for a lot of things. I spent some time to understand that options should be passed in /etc/modprobe.d/g_mass_storage.conf
It is finally seen in ubuntu. My problem is : it is in read only mode.
I tried to set the ro option to y or n without any impact on the behaviour. I changed permissions on the file (777), it changed nothing.
here is the current content of my /etc/modprobe.d/g_mass_storage.conf file :
options g_mass_storage file=/piusb.bin stall=0 removable=y ro=n
here is the of dmesg from the ubuntu :

What to do to get a read/write mass storage ?
I reproduced your problem. I had a similar problem with the module g_acm_ms on Raspberry Pi Zero W. If you configure the module in /etc/modprobe.d/, then the system ignores the parameter ro=0. Perhaps this is due to the order of initialization of kernel modules. I got around this by adding the module to the blacklist and writing the initialization in /etc/rc.local. Thus, I managed to get an emulation of a read/write mass storage.
All steps:
Create and format the file:
# dd bs=1M if=/dev/zero of="/piusb.bin" count=2048
# mkdosfs "/piusb.bin"
Add modules-load=dwc2,g_acm_ms to end of /boot/cmdline.txt (after rootwait)
Add the string dtoverlay=dwc2 in /boot/config.txt
Prevent module initialization at startup:
$ echo "blacklist g_acm_ms" | sudo tee -a "/etc/modprobe.d/blacklist-g_acm_ms.conf"
Add initialization in /etc/rc.local above exit 0:
# nano /etc/rc.local
Add string:
/sbin/modprobe file=/piusb.bin removable=y ro=0 stall=0
Reboot system:
# reboot -h
P.S.: If you don't want to use USB for console output, you can use g_mass_storage instead of g_acm_ms.

UDP send of XXXX bytes failed with error 11
I am running a WebRTC streaming app on Ubuntu 16.04.
It streams video and audio from Logitec HD Webcam c930e within an Electronjs Desktop App.
It all works fine and smooth running on my other machine Macbook Pro. But on my Ubuntu machine I receive errors after 10-20 seconds when the peer connection is established:

==> Btw, if I do NOT stream audio, but video only. I got the same error but only with the "video" between the Log lines...
somewhere in between the lines I also got one line that says:

It does not seem to help. I am still getting these errors and I experience lagging on the other side.
Additional info: on Ubuntu the Electronjs App connects to Heroku Server (Nodejs) and the other side of the peer connection (Chrome Browser) also connects to it. Heroku Server acts as Handshaking Server to establish WebRTC connection. Both have as configuration:
{'urls': 'stun:stun1.l.google.com:19302'},
{'urls': 'stun:stun2.l.google.com:19302'},
and also an additional Turn Server from numb.viagenie.ca
Connection is established and within the first 10 seconds the quality is very high and there is no lagging at all. But then after 10-20 seconds there is lagging and on the Ubuntu console I am getting these UDP errors.
The PC that Ubuntu is running on:
PROCESSOR / CHIPSET:
CPU Intel Core i3 (2nd Gen) 2310M / 2.1 GHz
Number of Cores: Dual-Core
Cache: 3 MB

Could please anyone give me some hints or anything that could solve this problem?
Thank you
==============EDIT=============
I found in my very large strace log somewhere these two lines:
7671 sendmsg(17, {msg_name(0)=NULL, msg_iov(1)=[{"CHILD_PING\0", 11}], msg_controllen=0, msg_flags=0}, MSG_NOSIGNAL) = 11
7661 <... recvmsg resumed> {msg_name(0)=NULL, msg_iov(1)=[{"CHILD_PING\0", 12}], msg_controllen=32, [{cmsg_len=28, cmsg_level=SOL_SOCKET, cmsg_type=SCM_CREDENTIALS, {pid=7671, uid=0, gid=0}}], msg_flags=0}, 0) = 11
On top of that, somewhere near when the error happens (at the end of the log file, just before I quit the application) I see in the log file the following:
https://gist.github.com/Mcdane/2342d26923e554483237faf02cc7cfad
First, to get an impression of what is happening in the first place, I'd look with strace. Start your application with
strace -e network -o log.strace -f YOUR_APPLICATION
If your application looks for another running process to turn the work too, start it with parameters so it doesn't do that. For instance, for Chrome, pass in a --user-data-dir value that is different from your default.
Look for = 11 in the output file log.strace afterwards, and look what happened before and after. This will give you a rough picture of what is happening, and you can exclude silly mistakes like sendtos to 0.0.0.0 or so (For this reason, this is also very important information to include in a stackoverflow question, for instance by uploading the output to gist).
It may also be helpful to use Wireshark or another packet capture program to get a rough overview of what is being sent.
Assuming you can confirm with strace that a valid send call is taken place, you can then further analyze the error conditions.
Error 11 is EAGAIN. The documentation of send says when this error is supposed to happen:
EAGAIN (...) The socket is marked nonblocking and the requested operation would block. (...)
EAGAIN (Internet domain datagram sockets) The socket referred to by
sockfd had not previously been bound to an address and, upon
attempting to bind it to an ephemeral port, it was determined that all
port numbers in the ephemeral port range are currently in use. See
the discussion of /proc/sys/net/ipv4/ip_local_port_range in
ip(7).
Both conditions could apply.
The first will be obvious by the strace log if you trace the creation of the socket involved.
To exclude the second, you can run netstat -una (or, if you want to know the programs involved, sudo netstat -unap) to see which ports are open (if you want Stack Overflow users to look into it, post the output on gist or similar and link to it here). Your port range net.ipv4.ip_local_port_range=1024 65535 is not the standard 32768 60999; this looks like you attempted to do something about lacking port numbers already. It would help to trace back to the reason of why you changed that parameter, and the conditions that convinced you to do so.

Please advice.
There are very few USB drives that work directly against an ESXi host, and versions prior to 6.0 had a very strict ruleset against mounting unsupported devices.
I'm assuming you're attempting to mount the USB drive as a VMFS volume, which is unsupported regardless of what version, however there is a list of supported devices that work for passthrough activities. I would assume these could be used as VMFS mounts as well: https://kb.vmware.com/kb/1021345
While it looks like you're following the proper steps, here's a detailed list that may help: https://kb.vmware.com/s/article/2065934
Alternatively, since USB performance is generally pretty slow on ESXi hosts, you could also perform your backup activities on the VM and then SCP the files off the ESXi host to the USB drive.

Means there is no transfer at all; this can be caused by wrong interface setting i.e.
u-boot is configured for 100Mbit full duplex, and you try to connect via half duplex or 10Mbit (or some mix of it). Another point is the MTU size, should be 1500 (u-boot cannot handle packet fragmentation)
Hint for windows/vmware users:
tftp timeouts from u-boot are caused by windows ip-forwarding.
1) If you have a home network : switch it of.
2) You are running Routing and Remote Access service : shut down service
3) check registry for ip forwarding:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\IPEnableRouter
set value to 0 (and maybe reboot)
